as always, Irulan, you have great advice.
To second her though, look where you want to go.... ahead....not infront of your wheel.
- speed: IS YOUR FRIEND

enjoy yourself, stay relaxed and go at the pace that you are comfortable with. I have said this a million times, I ride with other women, I enjoy the way that they can help my style and allow me to be the rider that I am. Try to find some other riders at your LBS, and I am sure that you will be hooked in no time.

Enjoy!
